COAL-SEPARATO R.

SPECIFICATION forming part of Letters Patent No. 427,124, dated May 6, 1890.

Application filed December 28, 1888. Serial No. 294,887- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. SEXToN, a citizen of the United States, residing at Dugger, in the county of Sullivan and State of Indiana, have invented certain new and useful Improvements in Coal-Separators, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improvement in an apparatus for screening and separating coal and other similar material; and it consists in the construction and arrangement of parts hereinafter described, and definitely pointed out in the claim.

The object of my invention is to arrange the several parts of my apparatus so that the process of screening coal and separating the several sizes or grades will be greatly facilitated and cheapened. I attain this object by the arrangement and construction illustrated in the accompanying drawing, wherein is shown a longitudinal vertical section of a building with may arrangement therein.

In the drawing, A represents the building having an elevator-shaft B, and 0 represents the track, which is located near the top of the building, and on which is placed a car or cars 0.

Located beneath the track is an inclined screen D, onto which the coal from the car is dumped, and through which the finer coal and slack pass. At the end of this screen is placed the dumping box or basket E, into which the large or lump coal passes.

Below the screen D is a hopper F, which has .a neck, as f, extending from its lower end.

This hopper is formed with inclined sides.

Below the hopper F is located a horizontally arranged revolving conical shaped screen G, whichis mounted on a shaft g, journaled in suitable bearings 011 cross-beams of the building. The end extending out from the small end of the screen is provided with a sprocket, cog, or pulley wheel f over which is adapted to be placed a chain or belt which connects it with an engine or other suitable motive power. The meshes of screen G are somewhat smaller than those of screen D. The lower end or neck of the hopper F is curved, as shown, and extends into the small end of the revolving screen, thereby conducting the contents of hopper F into the screen.

Situated below the revolving screen is a hopper H, into which the slack or finer material passes after passing through the meshes of the revolving screen. That portion of the coal which is too large to pass through the meshes of the revolving screen is conducted down its inclined sides and discharged from its lower or larger end into a hopper I.

K represents a chute, which is placed atan incline directly under the outer and lower end of the basket E, and conducts the coal down to the car below.

L L L represent cars placed, respectively, below the discharge ends of the hoppers H and I and chute K. By this arrangement it will be 'readily seen that the coal is separated and loaded without the employment of elevators or hoists which have been heretofore used. It will also be seen that the essential feature of my construction is the location of the screens and hoppers.

I am aware that inclining and revolving screens have heretofore been employed for separating coal, and these I do not broadly claim.

I am also aware that many minor changes in the construction and arrangement of the' several parts of my machine can be made and substituted for those shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The coal-separator herein described, consisting of an elevated track 0, on which a car is adapted to move, an inclined screen, as D, located below the track, a hopper, as F, below the screen, the rotating conical-shaped screen G, below the hopper and to one side of the same, and into which the hopper discharges, the hopper II, directly below the screen G, the hopper I at the end of same, and the basket E at the end of the screen D, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

- WILLIAM H. SEXTON.
